To help you assemble the Verde Cheyenne Rastor, look at the blades.  There aren't assembly instructions, just a guide.  The "E" blades are packaged on the inside of the group of blades and the fittings that screw on all face the same way - these are screwed in the BOTTOM rotator.  The "F" blades have fittings that face the opposite way and go on the TOP rotator.  Enjoy your spinner!
